From Science Daily:

ScienceDaily (Aug. 3, 2009) — It wasn’t that many years ago that the bowhead whale was written off as extinct in the waters around Greenland and especially in Disko Bay in northwest Greenland where University of Copenhagen has its Arctic Field Station.

But now the situation has changed and adult bowhead whales, which can grow up to 18 metres long and weigh 100 tons, have returned to the bay. This is probably because global warming has opened up the Northwest Passage, making it ice free at certain times of the year for the first time in 125,000 years. This gives bowhead whales from the northern Pacific a chance to reach Disko Bay and mate with the small local population.

A Look at Whether Increased Automation Means that Planes Will be More Dangerous.

Ben Cave was starting to get bored. The Australian had been sitting in his seat for more than three hours, and he still had two hours left before the Qantas jet was scheduled to touch down in Perth.

The Airbus A330 was flying at a cruising altitude of 11,278 meters (37,000 feet). The calm of modern jet travel, accentuated by the monotonous drone of the engines, prevailed on board the aircraft. The flight attendants were clearing away the last of the lunch trays into their trolleys, some of the 303 passengers were waiting near the toilets, and others were passing the time with stretching exercises.

Domestic Dog Origins Challenged

Domestic dog origins challenged

From BBC News:

The suggestion that the domestic dog originated in East Asia has been challenged.

The huge genetic diversity of dogs found in East Asia had led many scientists to conclude that domestication began there.

But new research published in the journal PNAS shows the DNA of dogs in African villages is just as varied.

An international group of researchers analysed blood samples from dogs in Egypt, Uganda and Namibia.

Today's dogs are descended from Eurasian grey wolves, domesticated between 15,000 and 40,000 years ago.

After The Boom, Is Wikipedia Heading For Bust?

From New Scientist:

Wikipedia has rapidly become one of the most used reference sources in the world, but a new study shows that the website's explosive growth is tailing off and also suggests the community-created encyclopaedia has become less welcoming to new contributors.

Ed Chi and colleagues at the Palo Alto Research Center in California warn that the changes could compromise the encyclopaedia's quality in the long term.

"It's easy to say that Wikipedia will always be here," says Chi, a computer scientist. "This research shows that is not a given."

Living Near A Wind Farm Can Cause Heart Disease, Panic Attacks And Migraines

Turbines: Ministers want to see another 4,000 across the country, meanwhile new research shows living near wind farms could damage your health.

From The Daily Mail:

Living close to wind farms can lead to a greater risk of heart disease, panic attacks and migraines, according to a study.

The farms can cause 'wind turbine syndrome', the symptoms of which also include tinnitus, vertigo and sleep deprivation, research to be published later this year claims.

Dr Nina Pierpoint, a leading New York paediatrician, says her five-year study of people living near wind turbines in the U.S., Britain, Italy, Ireland and Canada has led her to believe that they can also trigger nightmares in children and stop their brains developing properly.

Trees Are 'Crucial Famine Food'

From The BBC:

Trees can serve as a vital "famine food" to keep drought-hit communities alive when all other food crops fail, according to campaigners.

Food insecurity is a routine fact of life for many of the world's poorest people, Miranda Spitteler, chief executive of Tree Aid told BBC News.

She said the West needed to recognize the important role trees could play in reducing the need for conventional aid.

She also called for support for a local tree-based solution to food shortages.

From Live Science:

When President Barack Obama said in his weekly radio address Saturday that innovation would be a key to the future of the nation, he probably was not thinking specifically of artificial brains or replacement eyeballs.

But other researchers already have such goals in mind and are well on their way to building Humans 2.0, the real-life Steve Austin of the "Six Million Dollar Man."

Recent breakthroughs in bionics and lab-grown body parts — along with news last month that a Swiss research team aims to recreate the intricacies of the human brain within a decade — show science is rapidly creating many of the parts needed to build a fully functional human almost from scratch.

Comet Formation Theory May Not Be Set In Stone (Or Ice)

Photo: CLOUDY ORIGINS: A comet called 2001 RX14 likely originated from a hypothesized region called the Oort cloud, far outside the planetary region of the solar system. A new model of how comets wind up near the inner planets may revise estimates of the Oort cloud's properties. Mike Solontoi/University of Washington

From Scientific American:

A new model for comet production revises the theory of their origins.

A few times a year, a visitor from deep space swings by Earth's neighborhood. Usually coming in peace, these interlopers pass by close enough to be seen, then continue on their way.

The uninvited guests are comets, streaky globules of ice and dust dislodged from one of their usual haunts far from the sun and planets: the Oort cloud. Named for Dutch astronomer Jan Oort, who hypothesized its existence in 1950, the theorized cloud is thought to contain billions or even trillions of comets that range out a few thousand to tens of thousands of times as far from the sun as Earth is. Oort cloud comets are occasionally nudged onto trajectories carrying them into the inner solar system by the passing of nearby stars or other interactions with the rest of the Milky Way Galaxy.
